| 20110084917 | Haptic feedback device and electronic device - A haptic feedback device includes: a haptic device receiving a contact pressure applied thereto; and an actuator provided to the haptic device and excited according to a change in the contact pressure of the haptic device to generate vibrations. | 04-14-2011 |
| 20110090153 | Haptic feedback device and electronic device - A haptic feedback device includes: a haptic device receiving a contact pressure applied thereto; a vibration plate attached with the haptic device by means of an anaerobic adhesive and transferring vibration; and an actuator provided to the haptic device such that the vibration plate is interposed between the haptic device and the actuator, and excited according to a change in the contact pressure of the haptic device to generate vibration. | 04-21-2011 |
| 20110157035 | ACTUATOR MODULE - Disclosed herein is an actuator module that improves vibration of a touch screen pad. More specifically, the actuator module is configured to include a plate that is positioned at the lower part of a touch display module in which an image display unit is coupled to the lower part of a touch screen panel, a vibration generator that is positioned at the lower part of the plate and is mechanically deformed by compression or contraction when voltage is applied, and an adhesive layer that bonds the touch display module to the plate and the plate to the vibration generator and generates bending moment by the mechanical deformation of the vibration generator, thereby making it possible to transfer the vibration by the vibration generator directly to the touch screen panel and be designed in an ultra-thin type. | 06-30-2011 |
| 20110163634 | PIEZOELECTRIC ACTUATOR MODULE - Disclosed herein is a piezoelectric actuator module. The piezoelectric actuator module includes a flat plate, two or more elastic members, and a piezoelectric element. The elastic members are provided on each of opposite ends of the plate in a longitudinal direction thereof and protrude perpendicularly from the plate in such a way that a first end of each of the elastic members is coupled to an electronic device. The piezoelectric element is provided on a first surface of the plate and transmits vibrating force to the electronic device. The piezoelectric actuator module includes a plate having on opposite ends thereof two or more elastic members, thus being capable of controlling vibrating force by changing the length of the plate and the number of the elastic members, in addition to reliably supporting piezoelectric elements provided on the plate. | 07-07-2011 |
| 20110163635 | PIEZOELECTRIC ACTUATOR MODULE - Disclosed herein is a piezoelectric actuator module. The piezoelectric actuator module includes a flat plate. An elastic member is provided on each of opposite ends of the plate in a longitudinal direction thereof, and protrudes perpendicularly from the plate in such a way that a first end of the elastic member is coupled to an electronic device. A plate-shaped elastic body is provided on a first surface of the plate. A piezoelectric element is provided on a first surface of the elastic body. The plate-shaped elastic body is provided between the plate and the piezoelectric element, so that the overall spring constant of the piezoelectric actuator module is lowered and thus the vibrating force of the piezoelectric actuator module is increased. | 07-07-2011 |
| 20110216027 | Haptic feedback device and electronic device - Disclosed are a haptic feedback device and an electronic device. The haptic feedback device includes: a haptic device to which contact pressure is applied; an actuator provided in the haptic device and excited according to a change in the contact pressure of the haptic device to generate vibrations; and a controller controlling the actuator to vibrate at a pre-set resonance frequency in a pre-set first operation mode and vibrate at a driving frequency different from the resonance frequency in a second operation mode set to be different from the first operation mode. | 09-08-2011 |
| 20110260843 | Haptic feedback device and electronic device - There is provided a lightweight, slim and compact haptic feedback device due to an actuator module constituted of a piezoelectric element and a vibration plate, and an electronic device having the same. The haptic feedback device includes a haptic device receiving contact pressure applied thereto, and an actuator module being in contact with a lower surface of the haptic device and excited according to variations in contact pressure with the haptic device to thereby generate vibrations. | 10-27-2011 |
| 20110260995 | Actuator module, haptic feedback device and electronic device - There is provided an actuator module, a haptic feedback device, and an electronic device having the same. The haptic feedback device includes a haptic device receiving a user contact applied thereto, and an actuator module generating vibrations according to the user contact applied to the haptic device. | 10-27-2011 |
